CAR-SEAT FRAME.

SPECIFICATION forming part of Letters Patent No. 782,841, dated February 21, 1905.

Application filed November 18, 1904. Serial No. 233,353.

To @ZL whom it' may concern:

Be it known that I, BENJAMIN F. FORTINER, of Camden, county of Camden, State of New Jersey, have invented an Improvement in Car- Seat Frames, of which the following is a specification.

This invention relates to the means for securing the outer upholstery or covering to the base of the main box-frame of car-seat cushions or backs, and is particularly adapted for fireproof constructions in which the main boxframe is formed of sheet metal.

It is the'objeet of the invention to effect a neat and secure fastening of the edges of the covering without the use of rivets, bolts, eyelets, or kindred devices, which are liable to tear and otherwise injure the covering.

In the drawings, Figure 1 is an inverted plan view of a car-seat frame embodying my invention with a portion of the springs and slats broken away to show the interior. Fig. 2 is a cross-section of the same on the line A A of Fig. 1. Fig. 3 is a cross-sectional view in perspective of part of the seat-frame, showing the clamping device before it is closed down or clamped; and Fig. 4 is a similar view showing the clamping device closed down.

The details of construction of the frame structure outside of the clamping' devices form no part of the present invention and may be varied to suit the ideas of the constructor.

As shown, the body of the structure consists of a rectangular sheet-metal frame c, of substantially C shape in cross-section, having' top and bottom flanges a a2, which may be curved or beaded at the edges, as at cf. The longest sides of the box-frame have their upper outer surfaces depressed, as at a3, to receive the ends of the transverse flat springs and the rivets L. These springs are preferably provided upon their under faces with a central strip bzof increased strength. Coiled springs (Z are bolted at their upper ends to the strips b L2, and their lower ends are supported by transverse stamped sheet-metal slats e, the ends of which are provided with feet @2, resting on theinner surface of the lower fianges a2.

Above the spring-plates is placed the upholstery or covering, which usually consists of a sheet of canvas c and a covering of outer material c, such as woven ratan. This upholstery or covering may be fireproofed.

The covering is pulled down over the boxframe and folded over the beaded portion a* with the edges extending more or less over the inner face of the flange a2, as shown at c2. The clamping-strip lnf is then applied. This clamping-strip has a longitudinal fiat portion n.3 and a hooked or curled edge lz, terminating in a clamping-jaw 01,2. lhen first applied, this edge n. is slightly upturned or open, so that it may be hooked over the flange a* and the edge of the covering' c with the flat portion n3 resting on the covering below the flange, as shown in Fig. 3. The hooked portion a is then compressed or clamped down and the jaw a2 is forced down upon the projecting edge c2 of the upholstery and clamps it upon the flange a2 inside of the bead ci, as shown in Fig. 4C. This affords a very strong' and eflicient fastening for the upholstery, and as no teeth, rivets, or other means are employed which penetrate the fabric there is less liability to tearing.

In the construction shown the clampingstrips on the long sides of the frame are formed with notches or openings of in the curled edge n'. These are intended to permit the ends of the slats e to extend over the clamping-strip and rest on the bead They are therefore unnecessary at the ends, where the hooked portions a are continuous.

The clamps may be made in long strips, as shown, or in short sections.

l/V hat I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a ear-seat frame, the combination of a box-frame having lower beaded flanges, a covering. of upholstery having' its edges brought under the lower beaded flanges and over upon the Lipper surface thereof, and clamps having a lower face resting on the upholstery under the iianges, and hooked portions extending over the beads and clamped down upon the edges of the upholstery on the upper faces of the flanges.

2. In a car-scat frame, the combination ofl a box-frame having lower beaded flanges, a covering of upholstery having its edges brought under the lower beaded flanges and over upon the upper surface thereof, and clamps resting on the upholstery under the flanges and having hooked portions extending over the beaded edges of the flanges and provided with a clamping-jaw n2 clamped down upon the edge of the upholstery on the upper face ofl the lianges.

3. In a car-seat frame, the combination of a box-frame having lower beaded flanges, a covering of' upholsteryY having its edges brought under the lower beaded flanges and over upon the upper surface thereof, and clamps consisting of' longitudinal strips resting on the upholstery under the flanges and having hooked portions extending over the beaded edges of the iianges and provided with a clamping-jaw n2 clamped down upon the edge of the upholstery on the upper face of the flanges said hooked portions being provided with notches or openings n", and transverse slats having' their ends extending through said notches or openings and resting at their extremities on the opposite lower flanges of the box-frame.

In testimony of which invention I hereunto set my hand.
